useful Improvements in orllelstin to the Construction of Hells, Airship-1 angers,

and other Struccures, of which the followiu is u specificscion. I

Lly invention relates to improvements 1n fiche method or process for constructing or dismounlsing lesge holls or buildings (us for instance for housing sir ships), which has been desciibed in the patent of the United. fi cotesjl lo. 1,032,284 previously granted to meduly 9,1912, end which consists in construciing a hall sectiouof any len h and comprising a number of trusses step y step, without scaffolding, by tilting up pemially .iinished trusses about the foot points of the ing on or attaching the next followin truss sections under the other or elevate aside. l Ven theisrusses are constructedas three ointed arches iihen during the construction l ngth es required during the process or": construction, s

lhe improvement of the recess consists in that the partially finishe hall sect-ion is tilted up about the foot points of the trusses during the construction, e. that the tilting sis tuliee. place about the foot points of usses at one side of the hall only, v y about the fool:- points of the lower o trussseccions. lothe first place the lowermost truss sections of the one longitudinzzml side of the hell section are constructed on the ground then the upper girders, lower girders end diagonal ties or braces for the following truss seciiions are jointed on Wnile the structure is on the round The structure is then tilted up about t e foot oints of the lowermost truss sections to a su cient extent to allow ihe bars or elements of the next truss section to-be connected together; then upper girders, lower girders, and diagonel orsces of she next following truss sec-- lionsere joinfied on and the structure is again tilled about the icon points of the lowermost limes sections to e eu'iiicient extentlowest points for the time being of the I These lutiermust there-i Store he shifted or changed and varied in to enable the bars that hevebeen jointed on i to be connected together to form the next truss section and so on until one half of the truss has been completed. Then in the some way the uppermost truss section of the other half truss is built on and its lowermost point is temporarily connected by a tension band or member with the foot oi the finished half truss, and then the succeeding; truss; sections, or their sub-sections of the other half truss are built on, the; tension band being always as for as possiblckconnected to the lowest point. i p i The advantages of the new method or process or that no scaffolding is requiredin erecting the 'hell or structure it being only necessary to employ hoisting devices at one' side Which only need to be shifted relatively short distances during the progress of construction. Moreover the one half of the truss can be entirely constructed Without putting in tension rods or inombers, as it represents a rigid been]. Afurther advanta 'e is that, at least during thesecond p01 tidn of "the operation. of erecting or setting up the hell, the tilting can always take place on, the ultimate bearers or supports of the finished hall. Thus the final work of leveling or adjusting the hall is extremelysiinplified.

The accompanying drawings represent by way of example the construction of such a hell in its various stages of progress.

Figures 1 to 13 are views" illustrating in face View a truss in the successive stages of constructimi, from (he commencemeru of the work, Fig. 1, to the completion of the truss, Fig. i3. Figj'll is :1 perspective view Patented Apr. 8, 1913.

of the extreme end of a hall section in course of construction, namely during the buildingon of the last truss section, and consequently when Hie erection of the hall is nearly complele. It will be seen from this figure fhat 'two trusses arculweys unil'cd into one rigid pail-of trusses by transverse and diagonal tie s or members and are'tilted orelcvated together by one hoisting frame or device.

truss and-its sections, or sub-sections, but it will be remembere that two trusses are always united into a pair during construction and are elevated ortilted together by a common hoisting frame, and that all the truss pairs appertaining to the hall section to be erected, or it may even be to the entire and finished.

.tion ordivislon of the truss sections is formed of anzouter girder,-an inner girder,

twoitran'sverse bars and a'diagonal brace,

each transverse bar at the same time apperftaining to two consecutive sub-sections or see- -'t1ons of the truss.

, The lowermost truss sec tion a of the left half truss and the lower truss section f of the right half truss each consist of six sub-sections. The lowest of b of the next truss these" a. and

bearer of the anchored in the ground. First the truss section a is constructedon the ground (see Fig. 1) then the upper girder, lower girder and iagonal brace for the ad oining sub-section section b are jointed to the right of section a. Then by means oftho hoisting frame /the truss'section a is tilted up about '13 as a fulcrum to a suflicient extent to enable the sub-section 6 to be completed lates r w which in the finishing I after the second transverse bar has been fitted in (see Fig. 2)

Then the upper girder, lower girder and the diagonal brace of the next sub-section 6 are jointed to the structure, and the bea'm formed by the-truss section' a and subsection b about the point t suificiently to allow the subsection b to loo-finished (see Fig.3). In this position the upper and lower irders and the diagonalbrace of the next suh section 0 ere'jointed on. The hoistingframe g is now moved toward the right, and the structure thus far completed is again tilted up aboilt t high enough to enablesub-section (2 to be completed (see Fig. 4-). VVith the hoisting frame 9 in the same position, the structure is now further raised to a sufficient extent to allow of connecting together the upper girder and lower girder of the next sub scction 0 which meetat the crown h of the truss (see Fig. 5). The hoisting frame 9 is then again moved a suitable distance to the right, and the left half truss a, b, c is raised high enough to enable the next sub-section el to be put together, (see Fig. 6), and a tension rod 2 connected (see Fig. 7). The succeeding sections (Z etc, are built on similarly. In the further progress of the construction the tension, rod must be changed time and connected to lower points of the righthalr". truss. Thus as the construction proceeds the rod 2 (Figs. 7 and 8) must be changed for the tension rod 2 (Figs. 9 and f form triangles r, s, t and 11,1), 1w. At the bottom points 9 and w are fixed theall r'est upon the bearers a: and 3 are tilted higher from time to 10) and this for the tension rod s ain for the tension rod .2 (Fig.

bearer plate r alreadyrests on the bearer w, and in the further'tilting, the truss always turns on the axis of the bearer m. In the position shown in Fig. 8 where the sub-section e is being built on, this sub-section is shown shortly before it has been completed or connected together, the upper and lower girders and diagonal brace that have been jointed on the end of the preceding sub-section being seennot yet connected together. In the positions shown respectively in Figs. 9, 10, 11, and 12, the truss sections o f, f and f are respectively built on to ,the struc' ture. ---To permit of elevating the structure from the position of Fig. 10 to that of Fig. 11, the tension rod must be considerably lengthened, z'. 0., crown h by the jointed lmlf-trusses must be increased as otherwise when the structure is being elevated, the outer girder of sub section 1 would foul the top beam or head 9 of tie hoisting frame which serves for hoisting a pair of trusses. By suitably regulating the length of the tension rod the trusses can be prevented from fouling the top bar 9 of the hoisting frame in the subsequent stages of lifting, and the final position of the two half trusses in relation to each other can be attained either gradually or at the end of the construction by suitably shortenin the tension rod, so that the bearer plate 11: hes on the bearer y.

I claim herein as my invention:
